Pacific Northwest Stream Flow and Temperature Maps for Salmon Vulnerability Assessment

Gridded data for stream flow and temperature across the Pacific Northwest, used to assess steelhead salmon vulnerability to climate change. The dataset was produced by the National Oceanic and Atmospheric Administration and applies a spatially explicit method for the 2030-2059 climate scenario. It evaluates exposure and sensitivity across four freshwater life stages: adult migration, spawning, incubation, and rearing.

Use Cases

• Assess salmon vulnerability to climate change based on projected stream temperature increases.
• Model habitat suitability under altered flow regimes based on extreme high and low flow projections.
• Prioritize conservation actions based on combined exposure and sensitivity rankings across the Pacific Northwest.
• Evaluate the effectiveness of landscape-scale resilience strategies like floodplain connectivity restoration.

Strengths

• Focuses on a specific climate change scenario for the years 2030-2059.
• Analysis covers four primary freshwater life stages of steelhead salmon.
• Provides a spatially explicit assessment across the entire Pacific Northwest region.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is provided in PDF format, which may require extraction for computational analysis.
